Please note that when adding these optimized functions as default memset
memcpy functions in U-Boot, U-Boot fails to boot on the LX2160ARDB.
After the initial ATF output, no U-Boot output is shown on the serial
console. Some exception is triggered here in the very early boot process
as some of the assembler opcodes need the caches to be enabled.
Because of this, some additional patches will introduce memset_simple()
which will be used in some selected code location.
Note:
I also integrated and tested with the Linux versions of these optimized
functions. They are similar to the ones now integrated but these ARM
versions are still a small bit faster.
Ah, so here's why you didn't use the kernel versions. Do the kernel
versions still have the cache issue?
Yes, same issue unfortunately.
Also, this should be reworded a
bit since you did introduce memset_simple before here.
Agreed. I missed this. I'll reword this in v2.
Thanks,
Stefan
